Product Summary

The MIC2954-07BM is a bulletproof efficient voltage regulator with very low dropout voltage (typically 40mV @ light loads and 375mV @ 250mA), and low quiescent current (120uA typical). The quiescent current of the MIC2954-07BM increases only slightly in dropout, thus prolonging battery life. Key MIC2954-07BM features include protection against reversed battery, fold-back current limiting, and automotive load dump protection (60V positive transient). The MIC2954-07BM is an adjustable version that includes an error flag output that warns of a low output voltage, which is often due to failing batteries on the input. This may also be used as a power-on reset. A logiccompatible shutdown input is provided which enables the MIC2954-07BM to be switched on and off. This part may be pinstrapped for 5V output, or programmed from 1.24V to 29V with the use of two external resistors. The MIC2954-07BM applications are: (1)Battery powered equipment; (2)Cellular telephones; (3)Laptop, notebook, and palmtop computers; (4)PCMCIA VCC and VPP regulation/switching; (5)Bar code scanners; (6)Automotive electronics; (7)SMPS post regulator/dc to dc modules; (8)Voltage reference; (9)High efficiency linear power supplies.
